Floatable vessel

ABSTRACT

A floatable vessel is associated with an excavated area or foundation such that the floatable vessel rises and falls with changes in the water level of the surrounding environment. The foundation comprises a plurality of stabilizing posts that include telescopic sections where an upper telescopic section is connected to the floatable vessel. As the water level in the foundation rises or falls, the telescopic sections extend or retract as the buoyant floatable vessel moves with the water level. This action maintains the floatable vessel&#39;s connection with the foundation at various water levels. When there is no water within the foundation, or when the water level is sufficiently low, the floatable vessel rests on a plurality of pillars within the foundation. A tether cable is provided within the stabilizing posts as a back-up securing structure. Pivoting grates bridge the gap between the floatable vessel and the surrounding land.

PRIORITY

This application claims priority to U.S. Provisional Patent Application Ser. No. 61/271,289, filed Jul. 20, 2009, entitled “FLOATABLE METAL FOUNDATION OR VESSEL,” the disclosure of which is incorporated by reference herein.

BACKGROUND

Our world has been, and will continue to be, impacted by different types of water-related disasters. For instance, some water-related disasters may be caused by hurricanes, tornados, earthquakes, tsunamis, flash floods, seasonal storms, rising sea levels, among other causes. When such water-related disasters occur, loss of life and property can be extensive. Additionally, expensive and time-consuming repair and rebuilding efforts often follow such water-related disasters.

While a variety of efforts and strategies have been deployed to address such water-related disasters, it is believed that no one prior to the inventor has made or used an invention as described herein.

DETAILED DESCRIPTION

The following description of certain examples of the invention should not be used to limit the scope of the present invention. Other examples, features, aspects, embodiments, and advantages of the invention will become apparent to those skilled in the art from the following description. As will be realized, the invention is capable of other different and obvious aspects, all without departing from the invention. Accordingly, the drawings and descriptions should be regarded as illustrative in nature and not restrictive.

FIGS. 1 and 2 illustrate an exemplary foundation (100) associated with a floatable vessel (200) having a hull (300) and structure (400). Additionally, FIGS. 20-23 illustrate connecting grates (500) that bridge floatable vessel (200) to the surrounding land. These components and their subcomponents, will be described in greater detail in the following paragraphs.

I. Foundation

In the illustrated version shown in FIG. 1, foundation (100) comprises an excavated area of earth beneath and surrounding floatable vessel (200). Foundation (100) further comprises a liner (110), pillars (120), a sump pump (130), and stabilizing posts (140). These components of foundation (100), and their subcomponents, will be described in greater detail in the following paragraphs.

Encasing foundation (100) is liner (110). Liner (110) comprises walls (111) and floor (112). In the present example, liner (110) is made from concrete, although other materials for liner (110) will be apparent to those of ordinary skill in the art based on the teachings herein. For example, some suitable other materials may include brick, stone, other masonry block, among other materials with adequate strength and integrity to support floatable vessel (200) within a defined space and also securely hold stabilizing posts (140) as described further below. In the present example, walls (111) of liner (110) are connected either directly or indirectly through other intervening structures to completely line the sides (101) of foundation (100). Also in the present example, walls (111) further connect with, either directly or indirectly through other intervening structures, floor (112). Floor (112) extends inward from walls (111) to completely line the base (102) of foundation (100). The thickness of liner (110) may be of any suitable dimension. Various suitable thicknesses for liner (110) will be apparent to those of ordinary skill in the art in view of the teachings herein.

Pillars (120) are positioned along floor (112) of liner (110). In the present example, pillars (120) comprise poured concrete structures that are unitarily formed with floor (112) of liner (110). In some other versions, pillars (120) comprises separate structures altogether that may be fastened to floor (112), or that may be of sufficient mass such that pillars (120) generally remain in a desired position. While in the present example pillars (120) are constructed of concrete, in view of the teachings herein, other suitable materials of construction for pillars (120) will be apparent to those of ordinary skill in the art. As shown in the illustrated versions of FIGS. 1 and 2, pillars (120) are configured to support floatable vessel (200) when the water level within foundation (100) is sufficiently low (e.g., when the water level is such that floatable vessel (200) is not yet afloat). Also in the present example, pillars (120) are equally spaced to share the distribution of the weight of floatable vessel (200). Of course in some other versions the spacing of pillars (120) may be unequal. Pillars (120) are further configured such that the top surface (121) of each pillar (120) is level and each of the top surfaces (121) is level with each other. This level configuration ensures that floatable vessel (200) is supported in a level position when the water level within foundation (100) is sufficiently low that floatable vessel (200) is not afloat. Pillars (120) may be configured with any desired height. In the illustrated version shown in FIG. 1, pillars (120) have a height that permits access beneath floatable vessel (200) for cleaning, inspection, and maintenance while also generally aligning structure (400) of floatable vessel (200) with the ground surrounding foundation (100).

In the present example, sump pump (130) is located at one end of foundation (100); of course in other versions sump pump (130) may be located centrally within foundation (100) or in any other suitable location. In the present example, floor (112) of foundation (100) is sloped such that water collected within foundation (100) will drain towards sump pump (130). Sump pump (130) is connected with a drain pipe (131) that carries the water away from foundation (100) when sump pump (130) is activated. Sump pump (130) may be of any suitable design, and suitable sump pumps (130) for use with foundation (100) will be apparent to those of ordinary skill in the art based on the teachings herein.

In the present example, stabilizing posts (140) are positioned along the perimeter of foundation (100) at each end. Stabilizing posts (140) comprise a base (141) and an extending section (142). In the present example, base (141) of each stabilizing post (140) is recessed into base (102) of foundation (100) and held securely in place by the adjacent walls (111) and floor (112) of liner (110). In some versions, stabilizing posts (140) are secured to the bedrock beneath foundation (100) by suitable fastening structures that will be apparent to those of ordinary skill in the art in view of the teachings herein. In some other versions, floor (112) of liner (110) extends over each base (141) of each stabilizing post (140) to securely hold stabilizing post (140) within foundation (100). Those of ordinary skill in the art will appreciate other ways to securely position stabilizing posts (140) within foundation (100) in view of the teachings herein. As will be described in greater detail below, extending sections (142) are selectively, yet securely, connected with floatable vessel (200).

As shown in FIG. 2, each extending sections (142) of stabilizing posts (140) comprise first telescoping member (143), second telescoping member (144), and third telescoping member (145). As will be described in greater detail below, in the present example the third telescoping member (145) is selective, yet securely, connected with floatable vessel (200), and the first telescoping member (143) is connected with base (141). In some versions first telescoping member (143) is formed unitarily with base (141) and does not itself have any telescoping motion, yet it houses other telescoping members (144, 145). As shown in FIG. 1, when the water level within foundation (100) is sufficiently low, second and third telescoping members (144, 145) reside within first telescoping member (143). Yet, as shown in FIG. 2, when the water level within foundation (100) is sufficiently high, second and/or third telescoping members (144, 145) extend upward from first telescoping member (143) due to the upward force exerted on these telescoping members (144, 145) from the buoyant forces associated with floatable vessel (200). This movement of extending section (142) and its telescoping members (143, 144, 145) allows for floatable vessel (200) to remain linked with foundation (100) over a range of water levels that may exist from time to time based on the environmental conditions and circumstances. While in the present example, the buoyant forces associated with floatable vessel (200) cause the telescoping action of telescoping members (144, 145), it will be apparent to those of ordinary skill in the art in view of the teachings herein that in other versions such telescoping action may be accomplished or assisted by one or more driven motors or other mechanical devices.

In the present example, stabilizing posts (140) are constructed from marine grade stainless steel, however, other materials of construction may be used in addition to or instead of marine grade stainless steel. In any event, the materials used for stabilizing posts (140) should have adequate corrosion resistance and be able to withstand marine environments and prolonged exposure to water. Based on the teachings herein, other materials for constructing stabilizing posts (140) will be apparent to those of ordinary skill in the art.

The telescoping functionality of extending section (142) may be accomplished in a variety of ways. In the illustrated versions shown in FIGS. 2-4, telescoping members (143, 144, 145) fit together such that third telescoping member (145) is operable to fit within second telescoping member (144), and second telescoping member (144) is operable to fit within first telescoping member (143), as described above. In the present example, first telescoping member (143) is formed unitarily with base (141); of course in other versions first telescoping member (143) may instead be formed separate from base (141) and connected with base (141) by any suitable fastening means. In the illustrated version of FIG. 4, at the opposite end from base (141), first telescoping member (143) comprises an inwardly extending flange (146). At the same time, second telescoping member (144) comprises an outwardly extending flange (147) at one end and an inwardly extending flange (148) at the opposing end of second telescoping member (144). Third telescoping member (145) comprises an outwardly extending flange (149) at one end as well. As shown in FIG. 4, telescoping members (143, 144, 145) fit together such that inward and outward flanges of telescoping members (143, 144, 145) contact each other when telescoping members (143, 144, 145) are extended as shown in FIG. 2. Still other configurations for telescopically or movably connecting telescoping members (143, 144, 145) will be apparent to those of ordinary skill in the art in view of the teachings herein. Furthermore, while the present example has been described including three telescoping members (143, 144, 145), more or fewer telescoping members may be used.

As discussed previously, an upper portion of extending section (142) connects floatable vessel (200) with stabilizing post (140), which ultimately connects to foundation (100), thereby linking floatable vessel (200) with foundation (100). Various types of connections may be used to secure floatable vessel (200) to extending section (142). In the present example, an upper portion of third telescoping member (145) is welded to hull (300) of floatable vessel (200). In some other versions, a connecting bracket (not shown) is bolted or otherwise fastened to both an upper portion of extending section (142) and a connection point on hull (300). Still other connection types for securely connecting stabilizing post (140) to floatable vessel (200) will be apparent to those of ordinary skill in the art in view of the teachings herein.

Referring to FIGS. 2 and 3, in some instances the water level may rise to such a point that the buoyancy forces on floatable vessel (200) would cause stabilization posts (140) to extend past their full telescopic length. In such instances, stabilization posts (140) are configured with a break-away point (150) such that all or a portion of extending section (142) disconnects from the remaining portion of stabilization post (140). To retain floatable vessel (200) in a desired location, each stabilization post (140) is fitted with a tether cable (160) as described further below. In present example, break-away point (150) is configured as a weak point in stabilizing post (140) to ensure that when the stresses exerted on stabilization posts (140) are too great, stabilization posts (140) separate at break-away point (150). In some versions, break-away point (150) is configured such that separation at break-away point (150) is a destructive separation such that a new stabilization post (140) would be required to return stabilization post (140) to its non-separated configuration once the water level has declined. In some versions, break-away point (150) is configured such that separation at break-away point (150) is non-destructive such that the separation is repairable, e.g., the separate sections of stabilization post (140) may be readily reattached either without any required replacement parts, or without any significant required replacement parts.

In the present example, break-away point (150) is configured such that third telescoping member (145) separates from second telescoping member (144). In some other versions, break-away point (150) is configured such that extending section (142) separates from base (141). In some other versions, break-away point (150) is configured to occur at the connection point between extending section (142) of stabilizing post (140) and floatable vessel (200), such that stabilizing post (140) itself does not separate into two pieces, but instead separates from floatable vessel (200). Various modes for creating a break-away point (150) and reassembling a separated stabilization post (140), or reattaching a stabilization post (140) to floatable vessel (200), will be apparent to those of ordinary skill in the art in view of the teachings herein.

Tether cable (160) is configured as a safety structure that permits floatable vessel (200) to be moored to the home site in the event that the connection of the extending section (142) of stabilizing post (140) with floatable vessel (200) is compromised (e.g., by high water levels and the break-away feature described above, or due to other reasons). The term “home site” here is meant to represent an area associated with foundation (100). Of course areas associated with foundation (100) may be some distance away from foundation (100) itself (e.g., separated by many feet of flood water between foundation (100) and floatable vessel (200)). In the present example, tether cable (160) is of such a length to allow floatable vessel (200) to be linked to the home site when water level rises as much as about 10 feet above what stabilizing post (140) can accommodate; of course other lengths for tether cable (160) may be used instead, and such other lengths will be apparent to those of ordinary skill in the art in view of the teachings herein.

Referring to FIGS. 3, 4, and 8, tether cable (160) comprises quick release member (161), anchoring member (162), and tensioning member (163). As shown in the illustrated version, tether cable (160) is positioned within stabilizing post (140), and extends from base (141) to the top of extending section (142). Quick release member (161) is located generally at the top of tether cable (160), anchoring member (162) is located generally at the bottom of tether cable (160), and tensioning member (163) is positioned generally between quick release member (161) and anchoring member (162); although other locations along tether cable (160) may suffice for placement of quick release member (161), anchoring member (162), and/or tensioning member (163).

At quick release member (161), tether cable (160) is connected with floatable vessel (200). Referring to FIGS. 5-7, quick release member (161) comprises a coupling (166), a ring (167), and a pin (168). Coupling (166) connects to tether cable (160) and includes an opening (not shown) configured to receive pin (168). Ring (167) is configured with a gap (170) having flanges (171) that have respective openings (not shown) for receiving pin (168). In the present example, gap (170) and flanges (171) are configured such that openings of flanges (171) align with opening of coupling (166). This arrangement allows for pin (168) to pass through all openings for securely, yet selectively, connecting ring (167) to coupling (166). In some versions pin (168) is retained in place due to a tension force imparted on tether cable (160). In some other versions pin (168) is retained in place by other structural features (e.g., pin (168) and openings of flanges (171) may be threaded and thus pin (168) may threadably connect with openings of flanges (171)).

In the present example, ring (167) of quick release member (161) connects to floatable vessel (200) at receiving portion (310) of hull (300). Receiving portion (310) comprises a mounting member (311) and a locking hook (312). Mounting member (311) comprises a base (313) that is securely connected to hull (300) in the present example. Mounting member (311) further comprises a mounting portion (314) extending from base (313). Mounting portion (314) is configured with a passage (315) that permits a distal portion (316) of locking hook (312) to pass through passage (315). Mounting portion (314) further comprises an optional recess (321) that houses distal portion (316) of locking hook (312) when receiving portion (310) is in the locked position as described further below. A proximal handle portion (317) of locking hook (312) is selectively connected to an upper surface (318) of mounting portion (314) at lock (319). When disconnected from lock (319), handle portion (317) is operably configured to pivot such that the pivoting movement causes distal portion (316) to move within passage (315) and thereby create a separation between an underside (320) of mounting portion (314) and distal portion (316) of locking hook (312). When this separation exists, locking hook (312) can be considered in an unlocked state. When in the unlocked state, ring (167) may be either placed onto locking hook (312) or removed from locking hook (312). When handle portion (317) is pivoted in an opposite direction and joined with lock (319), any separation between underside (320) of mounting portion (314) is eliminated, thereby placing locking hook (312) in a locked state. In some versions, mounting portion (314) includes another passage that may replace recess (321) such that when in the locked stated, distal portion (316) is positioned into or through this other passage to emerge at or near upper surface (318) of mounting portion (314).

With the above configuration, a user can pivot handle portion (317) to the unlocked state to disconnect ring (167) and tether cable (160) from receiving portion (310) should such disconnection become necessary for safety or other reasons. Also, the configuration of ring (167) with pin (168) provides for another, or backup, disconnecting means should handle portion (317) be obstructed or inaccessible for any reason. While one mode of quick release connection between tether cable (160) and floatable vessel (200) has been shown and described, other various modes for a selective connection between tether cable (160) and floatable vessel (200) will be apparent to those of ordinary skill in the art in view of the teachings herein.

Tensioning member (163) is operably configured to maintain a desired tension on tether cable (160). Tensioning member (163) is further operably configured to manage slack in tether cable (160) and the amount of tether cable (160) that is let-out from stabilizing post (140) in situations where floatable vessel (200) has become separated from all or a portion of stabilizing post (140), or when extending section (142) has partially or fully extended. By way of example only, where floatable vessel (200) is being retained in position relative to foundation (100) only by tether cable (160), in some versions without tensioning member (163), all of the available tether cable (160) would readily be let-out regardless of whether the cause was rising water level or instead wind or water currents acting on floatable vessel (200). In versions with tensioning member (163), the mechanism for maintain tension are set within tensioning member (163) such that additional tether cable (160) will only be let-out by tensioning member (163) when a large enough force acts on floatable vessel (200) such that the tension in tether cable (160) exceeds the set-point used in tensioning member (163). Thus, for example, the set-point may be such to not let-out additional tether cable (160) when floatable vessel (200) is only being acted upon by common forces of wind or water currents. But at the same time, the set-point may be such to let-out additional tether cable (160) when floatable vessel (200) is being subject to rising water levels, or other sufficiently great forces (including e.g., uncommonly strong winds or water currents). Various ways to establish a set-point for tensioning member (163) will be apparent to those of ordinary skill in the art in view of the teachings herein. In the present example, the set-point is also adjustable, such that the desired amount of tension permissible in tether cable (160) can be adjusted. For example, a low tension may be acceptable when floatable vessel (200) remains securely connected with extending section (142) of stabilizing post (140), and a high tension may be desired when floatable vessel (200) has separated from extending section (142).

Although not required, in some versions tensioning member (163) may further be operably configured to draw-in slack in tether cable (160) when the forces acting on floatable vessel (200) have subsided to a point where there is, or otherwise would be, slack in tether cable (160) (including e.g., when floatable vessel (200) is still connected with stabilizing posts (140) and those posts (140) have telescopically retracted due to declining water levels). Such draw-in functioning may be accomplished in some versions through the use of a motorized reel or other structure that may be manually or automatically controlled. Various ways to configure tensioning member (163) to draw-in slack in tether cable (160) will be apparent to those of ordinary skill in the art in view of the teachings herein.

In some versions, tensioning member (163) comprises a spring-loaded member (164), as shown in FIG. 3, where one or more springs (not shown) provide the tensioning control. In other versions, tensioning member (163) comprises a counterweight member (165), as shown in FIG. 8, where one or more counterweights provide the tensioning control. Still in other versions spring-loaded member (164) and counterweight member (165) may be used in combination with each other or other devices. Various structures and designs for spring-loaded member (164) and/or counterweight member (165) will be apparent to those of ordinary skill in the art in view of the teachings herein.

At anchoring member (162), tether cable (160) is secured to stabilizing post (140) by a suitable fastening connection; of course tether cable (160) may be secured to structures other than stabilizing post (140) (e.g., a portion of liner (110)). In the illustrated version shown in FIG. 8, counterweight member (165) serves the dual function of tensioning member (163) and anchoring member (162). For example, tether cable (160) is securely attached to counterweight member (165), which extends below base (141) of stabilizing post (140) within chamber (169). Furthermore, base (141) is configured such that the opening (172) for tether cable (160) is of a size that it will not permit counterweight member (165) to pass through because of the width of counterweight member (165) being larger than the width of opening (172). In this configuration, when tether cable (160) is fully let-out, anchoring member (165) exists in that counterweight member (165) contacts base (141) at opening (172) thereby anchoring tether cable (160) to stabilizing post (140). Various other suitable fastening structures and fastening locations for use with tether cable (160) will be apparent to those of ordinary skill in the art in view of the teachings herein.

Referring to FIG. 3, base (141) of stabilizing post (140) also comprises an access panel (151). In the illustrated version, excess tether cable (160) is stored in base (141) within a compartment (152). In the present example, excess tether cable (160) is wound on a spool (not shown); of course other structures may be used to retain excess tether cable (160) as will be apparent to those of ordinary skill in the art in view of the teachings herein. Access panel (151) provides access to compartment (152) for servicing tether cable when needed. Within compartment (152), tensioning member (163) and anchoring member (162) are located. Therefore, access panel (151) also provides access to service tensioning member (163) and anchoring member (162) as needed. In some versions, compartment (152) also includes structural features that secure, or assist in securing, stabilizing post (140) to foundation (100) (e.g., pylons or other structures that secure base (141) into bedrock beneath foundation (100)). In such versions, access panel (151) provides access to service these structures as needed.

While the above paragraphs have shown and described versions of stabilizing posts (140) and their subcomponents or other associated components, certain modifications to stabilizing post (140) will be apparent to those of ordinary skill in the art in view of the teachings herein. For example, the number, as well as the dimensions, of stabilization posts (140) may be varied depending on the application. Also for example, some features may be omitted entirely from stabilizing posts (140). For instance, tensioning member (163) may be omitted, or tether cables (160) may be omitted entirely. Other modifications will be apparent to those of ordinary skill in the art in view of the teachings herein.

In the illustrated version shown in FIGS. 1-2, floatable vessel (200) comprises hull (300) and structure (400). These components and their subcomponents will be described in greater detail in the following paragraphs.

Hull (300) comprises sidewalls (330), a bottom (340), and a deck (350), which together define an interior (360). Referring to FIGS. 1-2, in the illustrated versions hull (300) is constructed of a suitable marine grade or marine treated metal; of course other materials of construction for hull (300) may be used and will be apparent to those of ordinary skill in the art in view of the teachings herein. Sidewalls (330) and bottom (340) of hull (300) may be configured as straight, sloped, or a combination. Hull (300) is configured to be water-tight, or at least substantially water-tight with the ability to pump out excess water taken-on (e.g., through use of a bilge pump or other pumping device). Hull (300) is buoyant such that hull (300) will float when surrounded on all sides by a sufficient amount of water. The configuration of hull (300) is such that it will accommodate whatever structure (400) will be located thereon (e.g., house, apartments, business, hospitals, airports, etc.), including the contents of structure (400) (e.g., furnishings, cars, personal affects, infrastructure devices, etc.). In some versions, hull (300) will accommodate twice the weight of structure (400) and its contents. In view of the teachings herein, various configurations and designs for hull (300) will be apparent to those of ordinary skill in the art.

Referring to FIG. 1, interior (360) includes a fresh water reservoir (361) and a waste reservoir (362). In the present example, fresh water reservoir (361) is positioned within the center of interior (360), away from sidewalls (330). Such positioning of fresh water reservoir (361) provides protection from any risk of puncture from something that could puncture sidewall (330) and also may assist in providing balanced floatation of floatable vessel (200); of course other ballast tanks may be used as well. Fresh water reservoir (361) may be of any suitable size; in the present example fresh water reservoir (361) is sized to satisfy at least three months of the requirements for structure (400). In some versions, when floatable vessel (200) resides on pillars (120) within foundation (100), the water supply from fresh water reservoir (36) is in continuous use and is continuously replenished by a connection to a well or community water supply. When floatable vessel (200) is raised off pillars (120) a sufficient amount due to increasing water level, the connection to a well or community water supply is broken or disconnected and the supply of water from fresh water reservoir (361) begins to be consumed without being replenished. In other versions, fresh water reservoir (361) may be separate from a continuous water supply and only used when such connection with a continuous water supply is broken. For instance, structure (400) may have connections to continuous water supply and if that connection is broken or disconnected, water from fresh water reservoir (361) may be accessed. Where the fresh water from fresh water reservoir (361) is not continuously supplied, the fresh water may be periodically changed out to ensure its purity. In view of the teachings herein, others ways to ensure the purity of the fresh water in fresh water reservoir (361) will be apparent to those of ordinary skill in the art. Various other configurations for establishing and replenishing water supplies similar to the above described manners will be apparent to those of ordinary skill in the art in view of the teachings herein.

Also in the present example, waste reservoir (362) is positioned within interior (360). In the illustrated version, waste reservoir (362) is located some significant distance away from fresh water reservoir (361). Waste reservoir (362) is configured to be connectable to plumbing fixtures of structure (400) such that waste water can be diverted to water reservoir (362) in the event that a connection with a septic tank or community sewer line is disconnected or otherwise compromised. The diversion of waste water may be accomplished through a series of valves or other structures as will be apparent to those of ordinary skill in the art in view of the teachings herein. The capacity of waste reservoir (362) is such to satisfy at least three months of requirements for structure (400); of course other capacities for waste reservoir (362) may be used as well, and will be apparent to those of ordinary skill in the art in view of the teachings herein.

In view of the teachings herein, it will be apparent to those of ordinary skill in the art that connections with external utility providers (e.g., water, sewer, electric, gas, etc.) to provide services to floatable vessel (200) when not afloat, are configured to be broken or disconnected and easily reconnected in the event that floatable vessel (200) becomes, or will become, afloat due to rising water levels or other reasons. Also, it will be apparent to those of ordinary skill in the art that such connections do not degrade the water-tight feature of hull (300). For instance, in some versions, all such connections to infrastructure items contained within interior (360) are made either through deck (350) or an upper portion of hull (300) which remains above water-level when floatable vessel (200) is afloat.

In addition to fresh water reservoir (361) and waste reservoir (362), interior (360) of hull (300) also contains other infrastructure devices and amenities. For example, a furnace, air conditioner, hot water heater, clothes washer, clothes dryer, air purifier, etc. can be located within interior and configured to be operable, through any suitable valve configurations, duct configurations (including appropriate venting of any combustion gases), connections, and disconnection means, when floatable vessel (200) is either residing on pillars (120) or afloat. Similarly, a generator can be positioned within interior (360) to provide electrical service when floatable vessel (200) is afloat. Such a generator may be adapted to use any suitable fuel, including propane or another fuel that may be contained within a tank located within interior (360). As with the other devices mentioned, suitable valve configurations, duct configurations (including appropriate venting of any combustion gases), connections, and disconnection means would also be used in conjunction with the generator. In some versions, all or some of these and other infrastructure devices and amenities may be located on deck (350) of hull (300) or within a structure (e.g. structure (400) or a separate structure) on deck (350).

As discussed above, hull (300) also comprises receiving portion (310), as shown in FIGS. 5 and 6. In the present example, receiving portion (310) attaches to sidewall (330); of course receiving portion (310) may connect to deck (350) instead or in addition to sidewall (330). Further description of receiving portion (310) is provided in the above section discussing foundation (100), and is not repeated here.

Referring to FIGS. 9-17, structure (400) is illustrated as a house (410); of course, structure (400) may be any other desired structure, including an apartment complex, an office building, a hospital, an airport, etc. In the present example, house (410) is located on deck (350) and is assembled, in large part, from precast cellular lightweight concrete (CLC) as described further below. Precast CLC is described in greater detail in U.S. Pat. No. 7,537,655, entitled “SLAG CONCRETE MANUFACTURED AGGREGATE,” issued May 26, 2009, and incorporated by reference herein. Of course other reinforced concretes, cellular concretes, or other materials, including those other than concrete, may be used for structure (400), and such materials will be apparent to those of ordinary skill in the art in view of the teachings herein.

In its construction, house (410) comprises I-beams (420), braces (430), and wall sections (440). As shown in the illustrated versions, braces (430) are securely fastened to deck (350) by bolts (431) and nuts (432); of course braces (430) may be welded to deck (350) or secured by other chemical or mechanical fastening means. Each brace (430) has a general U-shape with a base (433), and two sides (434). As shown in FIG. 14, each brace (430) also includes an optional insulator (435) that provides cushioning between base (433) and I-beam (420), which is to be secured to brace (430) as discussed in greater detail below. Insulator (435) is comprised of rubber in the present example, although other materials for insulator (435) will be apparent to those of ordinary skill in the art in view of the teachings herein. In some versions, insulator (435) covers bolts (431), while in other versions, insulator (435) is sandwiched between bolts (431) and base (430). Where insulator (435) is sandwiched between bolts (431) and base (430), washers (436) may be used. In view of the teachings herein, various other braces and/or modifications to brace (430) will be apparent to those of ordinary skill in the art.

As shown in FIGS. 12 and 15, I-beams (420) are securely positioned within braces (430) once braces (430) have been secured to deck (350). These erected I-beams (420) comprise a support frame (425) for subsequently attached wall sections (440) as will be described in greater detail below. I-beams (420) comprise flanges (421) and a web (422) extending between flanges (421) as shown in FIG. 9. This configuration provides I-beams (420) with their so-called “I” shape, where each I-beam has channels (423) extending along two sides of its length. In some versions I-beams are constructed from metal. In some other versions I-beams are constructed from CLC or other concrete. Based on the teachings herein, suitable types of metal and concrete will be apparent to those of ordinary skill in the art. To secure I-beams (420) within braces (430), in some versions bolts (not shown) are driven through sides (434) of brace (430) and into flanges (421) of I-beams (420). In some such versions, bolts (not shown) are aligned with web (422) such that bolts (not shown) will not interfere with the inserted wall sections (440) as described further below. As will be described further below, wall sections (440) also provide stabilizing and securing structure to I-beams (420). In view of the teachings herein, various other ways to securely position I-beams (420) within braces (430) will be apparent to those of ordinary skill in the art. For instance, in some versions, I-beams (420) may fasten directly, or through braces (430), to deck (350). Still in other versions, I-beams (420) may be extended below deck (350) and into interior (360) of hull (300), even to bottom (340) of hull (300).

As mentioned above, in the present example, wall sections (440) are precast from CLC and designed to fit within the recessed channels (423) of I-beams (420). As shown in FIG. 11, wall sections (440) comprise primary sections (441) and secondary sections (442). Secondary sections (442) are configured to fit within and substantially or completely fill the space provided by channels (423) of I-beams (420), as shown in FIGS. 13 and 16. Primary sections (441) are configured with a greater thickness compared to secondary sections (442). As shown in FIG. 13, this configuration provides that when wall sections (440) are installed between two I-beams (420) the outer surfaces (443) of wall sections (440) equal the thickness represented by I-beam (420) plus brace (430). In some versions, the thickness of primary sections (441) is such that when wall sections (440) are installed between two I-beams (420) the outer surfaces (443) of wall sections (440) equal the thickness represented by I-beam (420) alone, without regard to the additional thickness provided by brace (430). In view of the teachings herein, various other materials for wall sections (440) as well as ways to securely position wall sections (440) relative to I-beams (420) and braces (430) will be apparent to those of ordinary skill in the art. By way of example only, wall sections (440), once positioned within I-beams (420) and sitting upon deck (350), may be further secured to deck (350) by using sleeve anchors, or other structures, that may install from beneath deck (350) and into the bottom of wall section (440).

Referring to FIG. 17, a façade (450) for house (410) is constructed from mortar (451) and brick (452) in one version. In some versions, insulation (not shown) is included between brick (452) and the outer surfaces (443) of wall sections (440). As shown in the illustrated version, mortar (451) is applied to the outer surfaces (443) of wall sections (440) and outer surfaces (424) of flanges (421) of I-beams (420). Brick (452) is then secured to mortar (451) with deck (350) serving as a footer for brick (452); of course another structure may be installed over deck (350) to serve as a footer to support brick (452). While the present example illustrates and describes a façade (450) of brick (452) and mortar (451), other exterior façades (450) may be used instead of or in addition to brick (452) and mortar (451). Such other façades (450) will be apparent to those of ordinary skill in the art in view of the teachings herein, and may include things such as stucco, stone, concrete siding, wood siding, vinyl siding, among others.

Structure (400), and in the present example house (410) further comprises roof (460). Roof (460) is configured to withstand high winds, and based on the teachings herein, such suitable configurations for roof (460) will be apparent to those of ordinary skill in the art. For example, in some versions roof (460) comprises an underlayment of plywood sheeting (not shown), with an exterior covering (461) comprised of metal sheeting that is secured to the plywood sheeting. In other versions, ceramic tile or slate may be used instead of or in addition to the metal sheeting for exterior covering (461). In some versions house (410) comprises a plurality of trusses (not shown) that extend across and are secured to opposing wall sections (440). The plywood sheeting then may be secured to the trusses and the exterior covering (461) secured to the plywood sheeting. In some versions house (410) includes a metal framework (not shown) that is secured to wall sections (440) and provides an anchoring point to which to secure the plywood sheeting. It will be apparent to those of ordinary skill in the art in view of the teachings herein that roof (460) may be installed to accommodate any desirable and suitable pitch.

While the above paragraphs have described a “ground-up” type of construction where foundation (100) is constructed first, followed by floatable vessel (200), which includes hull (300) and structure (400), in other versions and applications, an existing structure (500) (e.g., a house) may be modified to be placed upon and secured to deck (350) of floatable vessel (200). In some versions, this is accomplished by structure (500) being jacked up using support beams (510) that distribute the weight of structure (500) to the surrounding land as shown in FIG. 18. Any existing foundation for structure (500) would be removed and the ground excavated to create foundation (100). In some versions where land is available adjacent structure (500), foundation (100) may be constructed separate from structure (500) and then structure (500) moved over to deck (350) after foundation (100) and hull (300) have been constructed. In some versions, existing structure (500) may be jacked up and then moved laterally such that existing structure (500) is not supportably hovering overhead as foundation (100) and hull (300) are being constructed in the place where the prior foundation was located. In view of the teachings herein, various ways to lift, lower, and laterally move existing structure (500) (e.g., a house) will be apparent to those of ordinary skill in the art.

Once foundation (100) and hull (300) are in place and structure (500) has been relocated, a metal framework (520) comprising a plurality L-shaped corner supports (521), and cross ties (522) is secured to deck (350). Metal framework (520) may also include braces (430) as described above. Metal framework (520) is configured to provide anchoring points for securing relocated structure (500) to deck (350). Various ways to secure existing structure (500) that has been relocated, to deck (350) of hull (300) will be apparent to those of ordinary skill in the art in view of the teachings herein.

Referring to FIGS. 20-23, a network of grates (600) are positioned around floatable vessel (200), connecting deck (350) to the surrounding land (601). Grates (600) thereby extend over the open space between walls (111) of liner (110) and deck (350) of hull (300). In the illustrated versions shown in FIG. 21A-C, grates (600) attach to liner (110) of foundation (100) at or near the upper portion of walls (111). Grates (600) further connect with liner (110) using hinged connections (602, 603). The hinged connections (602, 603) allow for grates (600) to pivot in two directions such that as foundation (100) fills with water and floatable vessel (200) moves upward, grates (600) pivot upward about hinged connection (602). Once floatable vessel (200) has moved upward sufficiently to pass grates (600), grates (600) pivot downward about hinged connection (603) such that grates (600) hang down walls (111) of liner (110) into foundation (100). In view of the teachings herein, other pivoting and movable configurations and operation for grates (600) will be apparent to those of ordinary skill in the art. By way of example only, in some other versions, a single hinged connection may be used that permits dual direction pivoting.

Grates (600) are configured with an open structure such that water can flow through grates (600), (e.g., in the case of a flood water passes through grates (600) and fills foundation (100)). At the same time, grates (600) have sufficient structural support and integrity to bear substantial weight and permit traffic to pass over grates (600). Grates (600) are constructed of a light-weight material as well. The manageable size of the individual grates (600), and their strong yet light-weight nature, permit the grates to be removed and reinstalled to reconnect deck (350) to surrounding land (601) once the water level has subsided and floatable vessel (200) is again residing on pillars (120). In some versions to remove and reinstall grates (600), a hinge pin (604) is removed, the grate (600) lifted from foundation (100) and repositioned appropriately, and then hinge pin (604) reinstalled. In some versions grates (600) comprise cut-out sections that leave room for extending section (142) of stabilizing posts (140). Various modifications, methods of using, and constructions materials for grates (600) will be apparent to those of ordinary skill in the art in view of the teachings herein.

In the present example, grates (600) further comprises a driveway grate (610). Driveway grate (610) comprises a reinforced grate sections (611) and a ladder (612). Reinforced grate sections (611) are constructed of any suitable materials that would provide sufficient strength to driveway grate (610) such that it can support vehicular traffic. In the present example, beams (613) extend along the length of driveway grate (610) and connect sections of grate (600) to create reinforced grate sections (611). In the present example, beams (613) are constructed from a suitably strong and durable metal. In view of the teachings herein, other materials of construction for beams (613) and other configurations for reinforced grate sections (611) will be apparent to those of ordinary skill in the art.

In the present example, driveway grate (610) is operably configured to pivot about a hinged connection (614) with deck (350) of hull (300). With this configuration, unlike grates (600), driveway grate (610) remains connected with deck (350) when floatable vessel (200) is afloat, with driveway grate (610) hanging downward from hinged connection (614) against sidewalls (330) of hull (300). In the present example, ladder (612) extends the length of driveway grate (610) to provide access to deck (350) when floatable vessel (200) is afloat and driveway grate (610) hanging downward along hull (300). Ladder (612) comprises rungs (615) that are securely connected with beams (613) and spaced accordingly to provide climbing access.

In some versions, driveway grate (610) is configured such that it can be slid onto the deck (350) and secured thereto. In such versions this may provide additional safety and security by making ladder (612) inaccessible to others not located on floatable vessel (200). In some versions, a motor driven system is configured to provide the retractable features of driveway grate (610). Of course the retractable nature of driveway grate (610) is not required in all versions, but where used it also permits a mode of reconnecting driveway grate (610) with surrounding land (601) once the water level has subsided and floatable vessel (200) is again residing on pillars (120). In versions without a retractable driveway grate (610), disconnection and reconnection about hinged connection (614) may occur in similar fashion as described above with respect to grates (600). In view of the teachings herein, other modes for providing a ladder (612) or other access to deck (350) via driveway grate (610), and imparting desired movement to driveway grate (610), will be apparent to those of ordinary skill in the art.

Referring to FIGS. 24-26, another exemplary floatable vessel (700) is shown where the living quarters are located within hull (300). In the illustrated versions shown in FIG. 24, a garage (710) is located on deck (350) that provides storage for vehicles or other items and also provides access to interior (360) of hull (300) to access the living quarters. Hull (300) is also configured with optional water-tight windows (720) and skylights (730).

While several of the illustrated and described versions focus on homes for structures associated with exemplary floatable vessels (200, 700), in view of the teachings herein, other structure types will be apparent to those of ordinary skill in the art. By way of example only, the structures and concepts taught herein may be adapted and scaled for use with such structures as nursing homes, grocery stores, hospitals, government or other office buildings, shopping outlets, and even air fields or airports. As illustrated in FIG. 27, an exemplary airport (800) is shown as the structure associated with a floatable vessel. As shown, the airport (800) comprises runways (801), a terminal (802), an access road (803), and a break wall (804). In view of the teachings herein, other structures for use with a floatable vessel will be apparent to those of ordinary skill in the art.

Having shown and described various embodiments of the present invention, further adaptations of the methods and systems described herein may be accomplished by appropriate modifications by one of ordinary skill in the art without departing from the scope of the present invention. Several of such potential modifications have been mentioned, and others will be apparent to those skilled in the art.
